Table 11. Light path diagnostics panel LEDs (continued)
• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• If a action step is preceded by "(Trained technician only)," that step must be performed only by a trained
technician.
LED Description Action
MEM An invalid memory configuration
(both the MEM LED and CONFIG
LED might be lit) or a memory
error has occurred . Note: Each time you install or remove a DIMM, you must
disconnect the server from the power source; then, wait 10
seconds before restarting the server.
1. If the MEM LED and the CONFIG LED are lit, the system
issues an invalid memory configuration error. Complete
the following steps to correct the problem:
a. Check the system-event log in the Setup utility or IMM
error messages. Follow steps indicated in Appendix
B “UEFI/POST diagnostic codes” on page 831 and
Appendix A “Integrated management module II (IMM2)
error messages” on page 327.
2. If the CONFIG LED is not lit, the system has detected a
memory error. Complete the following steps to correct
the problem:
a. Update the firmware to the latest level (see “Updating
the firmware ” on page 95).
b. Reseat or swap the DIMMs.
c. Check the system-event log in the Setup utility or IMM
error messages. Follow steps indicated in Appendix
B “UEFI/POST diagnostic codes” on page 831 and
Appendix A “Integrated management module II (IMM2)
error messages” on page 327.
TEMP The system temperature has
exceeded a threshold level. A
failing fan can cause the TEMP
LED to be lit. 1. Make sure that the air vents are not blocked.
2. Determine whether a fan has failed. If it has, replace it.
3. Make sure that the heat sink is seated correctly.
4. Make sure that the room temperature is not too high.
See “Server features and specifications” on page 6 and
“System reliability guidelines” on page 37 for the server
temperature information.
FAN A fan has failed, is operating too
slowly, or has been removed. The
TEMP LED might also be lit. 1. Check the LEDs on the server.
2. Reseat the failing fan, which is indicated by a lit LED on
the fan.
3. Replace the failing fan.
BOARD An error has occurred on the
system board. 1. Check the LEDs on the server.
2. Check the LEDs on the system board to identify the
component that caused the error. The BOARD LED can be
lit due to any of the following reasons:
• Battery
• Missing PCI riser-card assembly
• Failed firmware update
• Failed system board
3. Check the system-event log for information about the error.
4. Replace any failed or missing replacement components,
such as the battery or PCI riser-card assembly.
